Definitions

  • Aircraft seating configurations may provide for a seatback capable of breaking over during a dynamic event.
  • a passenger seat may broadly comprise a bottom chassis (upon which the passenger sits) and a seatback supporting the passenger's upper body, the rear of which seatback may face a second passenger sitting directly behind the passenger occupying the seat.
  • the seatback may comprise, for example, a tray table assembly, tablet holder, literature pocket, display screen and console, or any combination of these components.
  • the second passenger's head may be driven forward into the seatback, which may then pivot, or break over, to a full breakover position at a predetermined angle to the bottom chassis.
  • Seatback breakover may thus mitigate head and/or neck injuries to the second passenger due to a head impact with the seatback.
  • the resulting disparity in velocity between the seatback and the head of the second passenger may increase, rather than decrease, head injury and neck injury criteria (HIC, N ij ) and lead to preventable egress damage which may impede passenger egress from the aircraft.
  • HIC head injury and neck injury criteria
  • inventions of the inventive concepts disclosed herein are directed to a device for controlling the breakover rate (e.g., breakover velocity) of a seatback in response to a dynamic event.
  • the device includes a head injury criterion (HIC) link bracket attachable to the seatback and rigidly attachable to the seat frame, the bracket having a slot capable of accepting a HIC pin that transmits the breakover energy of the seatback.
  • the bracket may include breakover control elements fashioned of energy absorbing materials extending into the slot.
  • the breakover control materials engage with the HIC pin during the breakover event and restrict the breakover velocity of the seatback to optimize the velocity differential between the breakover velocity and the impact velocity of an object (e.g., a passenger, particularly the head thereof) colliding with the seatback during the dynamic event by absorbing at least a portion of the breakover energy transmitted by the HIC pin as it passes through the slot.
  • an object e.g., a passenger, particularly the head thereof
  • inventions of the inventive concepts disclosed herein are directed to a device for controlling the breakover rate of a seatback in response to a dynamic event.
  • the device includes a HIC link bracket to which breaking elements are attached.
  • the transit of the HIC pin through the slot (or a corresponding transit of a shearing link attached to the HIC link bracket and driven by the breakover energy of the seatback) is impeded, absorbing a portion of the breakover energy and restricting the breakover velocity to optimize the velocity differential between the breakover velocity and the impact velocity of an object (e.g., a passenger) colliding with the seatback during the dynamic event, by forcing the breaking element or the HIC pin to compress, bend, shear, or otherwise break one or more breakable elements of the HIC link bracket, the breakable elements being configured to fail upon absorbing a threshold level of energy.
  • inventions of the inventive concepts disclosed herein are directed to a piston-driven device for controlling the breakover rate of a seatback in response to a dynamic event.
  • the device includes a piston attached to the seatback at the rod end and to the seat frame at the barrel end.
  • a breakover event extends the stroke of the piston.
  • the barrel end of the piston may include compressible or energy absorbing materials configured to restrict the breakover velocity of the seatback to optimize the velocity differential between the breakover velocity and the impact velocity of an object (e.g., a passenger) colliding with the seatback during the dynamic event by impeding the extension of the piston and absorbing a portion of the breakover energy of the seatback.
  • inventive concepts are not limited in their application to the details of construction and the arrangement of the components or steps or methodologies set forth in the following description or illustrated in the drawings.
  • inventive concepts disclosed herein may be practiced without these specific details.
  • well-known features may not be described in detail to avoid unnecessarily complicating the instant disclosure.
  • inventive concepts disclosed herein are capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.
  • a letter following a reference numeral is intended to reference an embodiment of the feature or element that may be similar, but not necessarily identical, to a previously described element or feature bearing the same reference numeral (e.g., 1, 1a, 1b).
  • reference numeral e.g. 1, 1a, 1b
  • Such shorthand notations are used for purposes of convenience only, and should not be construed to limit the inventive concepts disclosed herein in any way unless expressly stated to the contrary.
  • any reference to "one embodiment,” or “some embodiments” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the inventive concepts disclosed herein.
  • the appearances of the phrase “in some embodiments” in various places in the specification are not necessarily all referring to the same embodiment, and embodiments of the inventive concepts disclosed may include one or more of the features expressly described or inherently present herein, or any combination of sub-combination of two or more such features, along with any other features which may not necessarily be expressly described or inherently present in the instant disclosure.
  • embodiments of the inventive concepts disclosed herein are directed to a system and related methods for regulating the breakover velocity of a seatback during a breakover event or similar dynamic event.
  • the breakover velocity can be restricted to achieve an optimal differential with the impact velocity of a passenger (or other object) colliding with the seatback, in order to reduce the risk of head or neck injury to the passenger or egress damage to the seatback.
  • an exemplary embodiment of a device 100 for controlling the breakover rate of a seatback 102 includes a head injury criterion (HIC) link bracket 104 fixed to the seatback 102 and the seat frame 106.
  • the HIC link bracket 104 may include a controlled traveling slot (108) capable of accepting a HIC pin (110) fixed to the seatback and capable of transferring the energy of the seatback 102 during a breakover event in response to a dynamic event (e.g., a rapid deceleration) whereby the seatback 102 breaks over from an upright position to a full breakover position (e.g., at a predetermined angle or orientation to a seat cushion or the floor of the vehicle interior in which the seat is installed).
  • the seatback 102 may break over at a breakover velocity in order to prevent injury to a passenger seated behind the seatback 102 (e.g., head injuries due to arm strikes) or to prevent damage to rear-mounted components of the seatback 102.
  • the head of the passenger may impact the seatback 102 (and be propelled generally forward into the seatback 102) at an impact velocity which may remain consistent or indicate acceleration as the passenger's head is propelled forward. If the differential between the breakover velocity and the impact velocity is too great, the mismatch in velocity between the seatback 102 and the passenger's impacting head may escalate the risk of injury to the head or neck of the passenger (e.g., increasing HIC or normalized neck injury criterion (N ij ) values). HIC characterizes the probability of injury to the head as a result of an impact, while N ij assesses injury to the neck due to the interaction of axial tensile and compression forces, and flexion (forward) and extension (backward) bending moments.
  • HIC characterizes the probability of injury to the head as a result of an impact
  • N ij assesses injury to the neck due to the interaction of axial tensile and compression forces, and flexion (forward) and extension (backward) bending moments.
  • HIC and N ij factors may influence HIC and N ij factors, including (but not limited to): the weight of the seatback 102; rear-mounted components or features of the seatback 102; the stiffness of the seatback 102 and/or seat frame 106; and the seat pitch, or the distance between one seat and the next.
  • the velocity mismatch may result in damage to rear-mounted seatback components that may impede egress from the aircraft.
  • the device 100 may be configured in a variety of ways to best control the breakover velocity so as to achieve an optimal differential between and the impact velocity.
  • a breakover event may be triggered by, e.g., rapid deceleration of the aircraft or vehicle.
  • the HIC link bracket 104 may be attached to the seat frame 106 by both a rigid attachment (112) and a breakaway attachment (112a) configured, e.g., to shear or fail upon absorbing sufficient energy to trigger a breakover event.
  • the breakover energy of the seatback 102 may be transmitted via the HIC pin 110 fixed to the seatback 102.
  • the device 100 may absorb a portion of the breakover energy, and thereby restrict the breakover velocity of the breakover (114) to optimize the velocity differential with the impact velocity, via energy absorbing breakover elements (116) capable of impeding the passage of the HIC pin 110 through the controlled traveling slot 108 or otherwise impeding the breakover energy of the seatback 102.
  • the energy absorbing breakover elements 116 may be fashioned of one or more of a metal, polymer, or composite material.
  • the breakover event (114) may extend from a time T 0 of initial impact (e.g., impact of the head with the seatback 102) to a time T F at which the full breakover position of the seatback 102 is achieved and breakover ceases.
  • the optimal velocity differential driving the degree to which the breakover velocity is restricted may comprise a range between an upper bound and a lower bound, or may be associated with a target velocity to which the breakover velocity is restricted.
  • the device 100 may prevent the breakover velocity from becoming either too high or too low.
  • HIC and N ij values corresponding to the risk of head or neck injury may increase if the seatback 102 (breakover velocity) breaks over either too rapidly or too slowly relative to the impact velocity.
  • the HIC and N ij values associated with a likely dynamic event may be optimized.
  • the HIC link bracket 104a may be implemented and may function similarly to the HIC link bracket 104 of FIG. 1 , except that the HIC link bracket 104a may include a "finger" or similar appendage (118) extending into the controlled traveling slot 108 capable of bending or deforming (118a) at a predetermined deformation rate in response to engagement by the seatback 102 (e.g., via the HIC pin (110, FIG. 1 ), absorbing the breakover energy of the breakover event (114) and restricting the breakover velocity.
  • a "finger" or similar appendage 118
  • the HIC link bracket 104a may include a "finger" or similar appendage (118) extending into the controlled traveling slot 108 capable of bending or deforming (118a) at a predetermined deformation rate in response to engagement by the seatback 102 (e.g., via the HIC pin (110, FIG. 1 ), absorbing the breakover energy of the breakover event (114) and restricting the breakover velocity.
  • the HIC link bracket 104b may be implemented and may function similarly to the HIC link bracket 104a of FIG. 2A , except that the HIC link bracket 104b may include within the controlled traveling slot 108, in addition to a primary appendage 118 configured to bend backwards upon engagement by the HIC pin (110, FIG. 1 ), one or more secondary appendages 120a-c. As the primary appendage 118 bends backward (118a) upon engagement by the HIC pin 110, absorbing the energy of the breakover event (114), the primary appendage 118 may sequentially engage the secondary appendages 120a-c, bending each secondary appendage 122a-c backward (118b-d) in succession.
  • the secondary appendages 122a-c may each be fashioned of a different material, or may have a different density or structure, such that, e.g., the secondary appendage 122a may absorb a greater quantity of energy, or deform at a different deformation rate, than the secondary appendage 122c.
  • the device 100a may be implemented and may function similarly to the device 100 of FIG. 1 , except that the device 100a may include a HIC link bracket 104 to which a deformable clip (124) may be attached.
  • the deformable clip 124 may be fashioned from any appropriate material or combination of materials and tunable depending on the desired deformation rate or optimal velocity differential.
  • the deformable clip 124 may include an engineered slot (126) through which the HIC pin 110 fixed to the seatback 102 passes as the seatback 102 breaks over (114) in response to the dynamic event.
  • the engineered slot 126 may restrict the breakover velocity by absorbing energy transferred by the HIC pin 110, providing resistance to the HIC pin as the HIC pin passes forward and deforms the engineered slot.
  • the engineered slot 126 may provide a variable deformation rate by offering variable resistance to the HIC pin 110 as the HIC pin progresses through the engineered slot 126.
  • the deformable clip 124 may be removably attachable to the HIC link bracket 104 without the use of specialized tools, and detachable with minimal force to aid in egress (e.g., so that the seatback 102 may be quickly and easily uprighted to facilitate rapid and safe evacuation in the event of an emergency) once the deformable clip 124 has deployed in response to a dynamic event.
  • the device 100b may be implemented and may function similarly to the device 100 of FIG. 1 , except that the HIC link bracket 104 of the device 100b may include a "nail” 128 or similar projecting appendage fashioned of energy absorbing material.
  • the HIC pin 110 passing through the controlled traveling slot 108 may "hammer" the "nail” 128 by forcing the "nail” through an orifice (130) having a diameter, or volume, smaller than that of the "nail” (128), absorbing the breakover energy by deforming the "nail” 128 and restricting the breakover velocity.
  • the material composition of the "nail” 128, and the dimensions of both the "nail” 128 and the orifice 130, may be selected to achieve the desired degree of energy absorption.
  • the device 100c may be implemented and may function similarly to the device 100 of FIG. 1 , except that the device 100c may include a HIC link bracket 104 wherein an energy attenuating insert (132) may be removably inserted into the controlled traveling slot 108, e.g., for one-time use.
  • an energy attenuating insert (132) may be removably inserted into the controlled traveling slot 108, e.g., for one-time use.
  • the material composition and geometric structure of the energy attenuating insert (132) may be tuned to absorb a particular amount of energy or deform at a particular rate (e.g., via a hollow tubular structure).
  • the energy attenuating insert 132 may be crushed during the breakover event (114).
  • the HIC link bracket 104c may be implemented and may function similarly to the HIC link bracket 104 of FIG. 1 , except that the HIC link bracket 104c may include a quantity of deformable material (134) (e.g., shearable, compressible, or bendable material) extending into, or adjacent to, the controlled traveling slot 108.
  • the deformable material 134 may be capable of regulating the breakover velocity by providing resistance to the seatback 102 ( FIG. 1 ) during a breakover event (114). For example, as the seatback 102 breaks over in response to a dynamic event, the HIC pin (110, FIG.
  • the composition and quantity of the deformable material 134 may be adjusted to achieve the desired degree of energy absorption.
  • the device 100d may be implemented and may function similarly to the device 100 of FIG. 1 , except that the device 100d may include a breaking element (136) rotatably coupled to the HIC link bracket 104.
